context_page_description: The Isaac Heffron House is a two-story building located at 1509 Postoffice Street in the East End Historic District of Galveston, Texas. The house was built by Isaac Heffron, a prominent Galveston contractor in the Victorian period and during the city's recovery from the 1900 Galveston Hurricane. Later, the house was the residence of T.J. Holbrook, a Texas state senator from 1922 to 1939.
context_section_description: The 1890 Isaac Heffron House is a two-story, four-bay, urban Victorian house with turned columns, a two-story tri-partite bay window, and a central entrance. Compared to other noted architectural examples of the period in the East End district, the house has more restrained details. Its placement on a constrained urban lot between other houses limited Heffron's ability to employ other common Victorian elements, such as turrets and wrap-around porches.
  The tall two-over-two windows of the first story are characteristic late nineteenth century features and they are indicative of the use of the porch as an extended living space in the subtropical climate. The rear, southern porch illustrated in the 1899 Sanborn Map is typical of north-facing houses that sought to capture incoming breezes from the Gulf of Mexico. While there is no evidence that Heffron hired an architect for the project, the lot bears signs of his personal influence as a contractor, most notably in the concrete balustrade at the front of the lot.
